Problems solved by technology

Years of market feedback information let us realize that if the customer's misoperation, small mistakes, and occasional accidents have to bear the consequences of damage to the parts and must be repaired before they can continue to be used, no matter for the mass production of the product or the quality of the product Popularization and promotion will have a negative impact
The serious failure of the fan heater due to abnormal use has plagued us for many years, and it has become a technical obstacle that we least expect to encounter but cannot be circumvented.

Embodiment approach 1

[0015] Embodiment 1. The heating power of the fan heater is 1600W, the operating temperature of the thermostat on the heating rack is 85°C, the operating temperature of the thermal fuse is 145°C, the mechanical switch timer, and the heating element is fixed inside the fan heater (1) The surface of the guide air duct (5) is fixed with a manual reset thermostat (4) with an operating temperature of 50°C. The thermostat is connected in series with the power line, or it can be connected in series in the heating circuit. The location is limited between the front end point (2) and the rear end point (3) of the fixed heating element installed in the guide air duct inside the fan heater. After the surface temperature of the air duct of the fan heater exceeds the operating temperature of the thermostat by 50°C, the temperature control The thermostat starts, cuts off the power supply, and stops heating. After that, the thermostat remains disconnected until the power cord plug is unplugged...

Embodiment approach 2

[0016] Embodiment 2. The heating power of the fan heater is 2000W, the operating temperature of the thermostat on the heating rack is 100°C, and the operating temperature of the thermal fuse is 150°C. The fan heater is equipped with an electronic circuit board switch timing control system. The guide air duct (5) of the heating element (1) is fixed inside the fan heater, and the manual reset thermostat (4) with an operating temperature of 50°C is fixed on the surface. The relative position of the manual reset thermostat is limited to the fan heater The inner guide air duct is installed between the front end point (2) and the rear end point (3) of the fixed heating element. The manual reset thermostat is connected to the electronic circuit board. When the surface temperature of the air duct of the fan heater exceeds the operating temperature of the manual reset thermostat by 50°C, the electronic circuit board controls to cut off the power supply and stop heating, and the motor is...

Abstract

The invention relates to a safety protection device for a fast bedding dryer. A temperature monitoring regulation device is added on the surface of an inner fixed heating body frame structure of a hot air supplying device, the inner fixed heating body frame structure of the hot air supplying device can be a guide air channel. The safety protection device monitors secondary damage information during abnormal work of the fast bedding dryer, judges the abnormal working condition through logic analysis, starts up quickly before the temperature of the dryer reaches the degree which can damage fan heater components to cut off a power supply and stop heating to avoid accidents and prevent a fan heater from being damaged by high temperature. After the full new safety protection device is started, a user can simply pull a power plug and insert the plug again to enable normal work to be restored.

Description

technical field [0001] The invention relates to a safety protection device for a fan heater, specifically, it is directly connected to a flexible air bag or an air cushion at the air collecting port or through a pipeline, or closely connected to a relatively independent and airtight heating space of a cabinet or box structure. The safety protection device installed inside the butt fan heater. Background technique [0002] The fan-type heater involved in the present invention is a heating body for heating, drying, dehumidification and moisture-proof equipment such as a quilt dryer, a quilt warmer, a cabinet dryer, and a dryer. The relatively independent and closed heating space of the cabinet or box structure provides continuous hot air flow. [0003] The air outlet of fan heaters seen in daily life is a wide-mouthed open structure, which is mainly used for heating. Overheat protection devices such as thermostats and thermal fuses are designed and installed on the mica boar...
